Subject[PATCH -tip 0/9] perf-probe updates - use elfutils and introduce lazy matching
Hi Ingo,

Here are several bugfixes and updates of perf-probe.
This updates includes moving onto elfutils-libdw and
the lazy line matching support which you had mentioned :-)

elfutils library is developed closely with gcc team,
and it is simple and fast dwarf analysis library.

lazy-matching is similar to glob matching but ignoring
spaces in both of target and pattern.

This is updated todo list. Most of them are related
to the 'type' support.

Long-term TODOs (future features):
- Enhance probe-finder to decode call frame instructions.
- Support sys_perf_counter_open (for non-root users)
- Support tracing static variables (non global)
- Support variable types from debuginfo (e.g. char, int, ...)
- Support fields of data structures (var->field)
- Support array (var[N])
- Support dynamic array-indexing (var[var2])
- Support string/dynamic arrays (*var, var[N..M])
- Support force type-casting ((type)var)
- Support the type of return value

- Better support for probes on modules
- --list option shows the file-name/line-number of each events.

Thank you,


Masami Hiramatsu (9):
perf probe: Add lazy line matching support
perf probe: show more lines after last line
perf probe: Check function address range strictly in line finder
perf probe: Use libdw callback routines
perf probe: Use elfutils-libdw for analyzing debuginfo
perf probe: Rename probe finder functions
perf probe: Fix bugs in line range finder
perf probe: Update perf probe document
perf probe: Do not show --line option without dwarf support
